There are major differences between the political system of the United States and that of most other developed democracies. These include greater power in the upper house of the legislature, a wider scope of power held by the Supreme Court, the separation of powers between the legislature and the executive, and the dominance of only two main parties. Third parties have less political influence in the United States than in other developed country democracies.

The federal object created by the U.S. Constitution is the main feature of the American governmental system. However, most people are also subject to a state government, and all are subject to various units of local government. The latter include counties, municipalities, and special districts.

The federal government was created by the states, which as colonies were established separately and governed themselves independently of the others. Units of local government were created by the colonies to carry out various state functions. As the country expanded, it admitted new states modeled on the existing ones.

In each state there are governors. They are in charge of their state. They make and pass bills that would become laws in their countries. There are also two senators who represent their state in congress. There are also representatives who represent a district in their state and also represent them in congress.

The President of the United States is the head of state of the United States. They are elected by the American citizens every four years in democratic elections. They also appoint people who will work in different departments that focuses on special areas for the country.
